T0 aZZ whom zt may concern:

Be it known that we, FRITZ VON KREMPEL- HUBER and JOSEPH VON SCHMAEDEL,C1ZGHS Of the Kindom Of Bavaria, residing ab Munich, Bavaria, in the German Empire, have inventedeertain new and useful Improvemenrs in Blowpipe Soldering Deviees, (for which WG have obtained patents in Germany, Oetober 12, 1891, N0. 59,209; in Austria-Hunga.ry, September 16, 1891, N0. 19,806 and N0. 37,878; in France,August 14, 1891,NO. 212,948; in Belgium, Ma v 15.1891,N0.94629; in Eng- 1and, April 23,1891, N0. 7,020. and in Switzer- 1and, August 7, 1891, N0. 3,830,) Of which the following is a specifieation.

In the drawings, Figure 1 is a. vertical elev a.tion, and Fig. 2 aplan, Of our soldering de- VIOO.

The apparatusinvolving 011I111V811131011 cousists in a heating-vessel O1 lan1p a, (for 2.100- h01 01 the like,) provided witn a. wick-tube b. Upon the first is mounted a vessel c, having a blowpipe d. A bentwire e is, moreover, secured t0 Ehe heating-vessel, which 1's rendered incandescent by the aetion Of the lamp and blowpipe and whieh at its end is provided with a sma1l shield f, formed Of suitable material. The wick b Of the lamp after the same is filledbeinglighted andairbeingblownthrongh the tube d into the flamme by a.ny suita.ble blowing device a blowpipe flame is produced whose point strikes the wire e and renders the Same incande scent a.0 its lower end. The shield f serves t0 concentrate Ehe blowpipe fiame and tO confine it to the point. Of the wire. 'lhis heated point, which may be Of a.ny suitable form, may then be used as aso1- dering-tool; but WO do not limit onrselves t0 this use, since it n1a.y also be used f01 engraving purposes, burning patterns into wood, o1 f0r operating upon all materials subjeet to the action Of heat. A disk Or shield s is detaehab1y secured t0 the wiek-tube d and serves the pnrpose Of insulating the alcohol-receptaele from the fla.me.

The air for the blowpipe flame may be introdueed by Ehe mouuh 01 by any suitable blower, (for instance, a rubbe1 bal1 and tube.) The blowpipe-flame might also be produeed by the pressure Of the evapora.ted material 01 fluid itself similar] y to the well-known blowpipe flamme. The lamp body 0[' receptaele may, moreover, be fil1ed with sponge, cotton, asbestus, O1 tshe 1ike for the purpose Of absorbingtheliquid fuel and retaining thesaune and preventing ehe spilling thereof.

What we olaim, and desire t0 secure by Letters Patent, is-

II1 a. blowpipe-larnp, a burner and blowpipe, in combination Witl1 a. heating-wire provicled nea.r its end with a shield for concentrating the blowpipe-flame, said blowpipe being arranged tO direet the blast throngh the flamme onto ehe shield, substantially aus Set forh.

In testimony thac we c1aim the foregoing as Our invention WG have signed our names in presence Of tWO subscribing witnesses.
